Answer:

  • a. $73.75
  • b. 57 rides

Explanation:

a.

Initial value of the pass is $100

From the difference in values we can see the cost of one ride is $1.75

The formula:

  • P(r) = 100 - 1.75r, P- the value of the pass, r- the number of rides

Value of the pass after 15 rides:

  • P(15) = 100 - 1.75*15 = 73.75

b.

Number of possible rides:

  • 0 = 100 - 1.75r
  • 1.75r = 100
  • r = 100/1.75
  • r = 57 (rounded to the whole number)
